Classic are our class pets gotten weaker in SL

I need help, so I am doing story missions in Shadowlands and my damn voidwalker keeps dying...The dude is so weak. What's going on? Like literally, he can't even handle more than 1 enemy. Sometimes my pet will die vs 1 enemy in Shadowlands. I am talking about my warlock pet, Voidlord/Voidwalker, aka the Tank. Are hunters facing the same issue? Why my pet is dying so much. Should I go demonology? Right now I am affliction. via /r/wow https://ift.tt/3z2BAMt
